Innovative astronaut navigation system based on smart integrated sensors

Original algorithms for navigation on the surface of Mars planet, especially applied to astronauts, are proposed in this paper. The autonomous navigation system for astronaut is based on inertial measurement unit (redundant) and Laser (redundant), which permits to localize and navigate in known environment and unknown environment constructing its map in real time, using adaptive algorithms and physical and natural constraints of astronaut´s body. The estimation of the position of astronauts is done using non linear adaptive filters such as the Extended Kalman Filter (EKF) and other non linear variant filters. Finally, additional smart idea is to use Phobos and Deimos as navigation constellation in addition to one more satellite.
